Complementarity between JWST and High Resolution Spectroscopy for characterization of Hot Jupiter Atmosphere

Hot Jupiters are giant gaseous planets, which orbit their host stars in a few days to hours. Due to these tight orbits, they are expected to rotate synchronously, ie always present the same face to their star. As a consequence, models predict these worlds to present strong westward winds, redistributing the heat from their permanent daysides to their cold nightsides. While indirect
jmethods have been used to corroborate these predictions, direct measurements of rotation/wind speeds on these objects remain
!elusive. ln this project, we aim to develop a novel method combining existing space and ground based approaches, which should
[allow for the first direct and constraining measurements of rotation and wind speeds in a Hot Jupiter atmosphere.

Experimental testing of coarse granular materials

One of our research axes concerns the large-scale mechanical characterization of coarse granular materials (CGM). The prime objective of this collaboration is to enhance the database and develop scaling laws for testing CGM on representative small-scaled samples. This effort requires multiscale characterization on a wide range of coarse materials with different lithologies and particle shapes. The collaboration with the Institute of Soil Mechanics and Rock Mechanics (IBF) at Karlsruhe Institute of Technology in Germany, helps to meet this end. IBF disposes one of the largest triaxial cells worldwide that allows testing samples of diameter D=780 mm (Hettler and Vardoulakis, 1984). However, this device has been often used for industrial projects but seldom for research purpose (e.g. Brauns & Reith 2000; Bettzieche & Bieberstein 2009). Therefore, this initiative intends also to resurface this device by taking advantages that it offers to the research community at large, to contribute on coarse materials testing database.

Performance of cavity nesting birds breeding onreclaimed mine lands: An individual life-historyapproach

This study will assess the behaviour, physiology, reproduction and survival of individual birds breeding on reclaimed mine tailings and waste rock, and will provide a robust measure of the effectiveness of reclamation efforts on the Highland Valley Copper operating area. By examining a range of life-history traits in two ecologically distinct species, and comparing birds breeding on reclaimed mine lands to those on land that has not historically been exposed to mining operations, we will also be capable of identifying individual measures of quality or reproductive investment that most closely track environmental disturbance. This may become the basis for future cost-effective impact assessments in all industrial sectors engaged in resource extraction, as individual responses to environmental disturbance can provide an “early warning’ of future population declines. It has been argued that effective natural resource management requires the application of evolutionary principles such as selection, variation and gene flow, and this study will position Highland Valley Copper, and Teck Resources Ltd. more generally, at the forefront of this approach in the context of impact assessment.

What confabulation in aging tells us about the episodic/semantic memory divide

The project investigates the distinction between two main forms of human memory, namely episodic (the experiential contextualized memory for personal past episodes) and semantic (the abstract de-contextualised memory for facts) memory. In line with recent proposals in philosophy, it calls this widely accepted distinction into question and explores a one-system conception of memory. The original angle taken on the issue appeals to the phenomena of semanticization and confabulation in aging, namely the tendency of episodic memories to become more semantic (semanticization), and the tendency of older adults to report more past personal episodes they never experienced (confabulation). On our overall proposal, semanticization and confabulation each cast doubt on the episodic-semantic distinction in their own way.
Three more specific outcomes are expected. 1) Coming to a better understanding of semanticization in light of confabulation and thereby deciding if it favors the one-system view. 2) Exploring the possibility that confabulation, a phenomenon that is most often episodic in format at first sight, is grounded on semantic memory. 3) Developing the view that confabulation is the inverse of semanticization, that is episodicization of semantic memory.

Travail et santé dans l’agroécologie : cas des maraichers en « bio »

Les enjeux de ce projet de recherche se situent dans les transitions du monde agricole, en lien avec le besoin de répondre à la biodiversité, en réponse à la préservation de la planète, au réchauffement climatique et aux changements de comportements alimentaires des consommateurs. Ces transitions transforment les pratiques des agriculteurs, notamment avec des effets sur leurs conditions de travail et leur santé. Ce projet cible les fermes en agriculture biologique dans le secteur du maraîchage. La recherche-action se déroulera en 3 étapes méthodologiques : 1/ état de la littérature sur les risques relatifs à l’agro-écologie, 2/ caractérisation des contextes des exploitations agricoles avec la recherche de bases de données disponibles et une enquête par entretiens, voire par questionnaires, pour dresser un portrait du secteur au Québec et 3/ un suivi d’une ferme avec une analyse ergonomique sur les risques en SST dans la province de Sherbrooke. L’étude sera supervisée par les 2 co-encadrantes professeures avec des réunions régulières. Le stage, d’une durée de 5 mois, à partir de mars 2024, vise à produire un rapport de recherche visant une meilleure connaissance sur les problématiques posées par ce secteur d’activité. Ce projet d’impulsion d’un partenariat de recherche entre l’Université de Grenoble et l’Université de Sherbrooke pourra permettre de s’engager dans des réponses à appel à projet de recherche ambitieux et international.

Électrolytes autoréparants pour un stockage électrochimique tout-solide efficace & durable de l’énergie : Microbatteries 2.0

Un défi scientifique et technologique contemporain majeur, contribuant à une réponse appropriée à l’ODD N°7 de l’ONU, consiste à impulser un changement de paradigme en passant des batteries lithium-ion (électrolyte liquide/gélifié) à des batteries dites tout-solides (électrolyte (inorganique, polymère) solide) plus sûres et performantes. Au-delà des accélérateurs de développements technologiques que constituent les domaines du stockage stationnaire et de la mobilité électrique, le développement de tels batteries post-lithium-ion est (très) attendu pour répondre à la demande croissante d’électronique embarquée miniaturisée à autonomie énergétiques renforcée (e.g. objets connectés [Io(E)T : Internet of (Every)Thing]). Pour relever ce challenge, nous proposons ici de combiner pour la première fois i) des électrodes négatives en Silicium à porosité multi-échelle contrôlée (produites à Sherbrooke, IRL3463-LN2@UdeS) infiltrées (à l’état fondu) par une nouvelle génération d’électrolytes solides polymères autoréparants et ii) des résines négatives 2.0 photosensibles doués de faculté de transport ionique (les SHPEs (Self-Healing Photopatternable Polymer Electrolytes)) conçus, synthétisés et caractérisés à Grenoble, UMR5279-LEPMI@UGA), c’est-à-dire respectivement 2 des 3 sous-composants (électrode (-)/électrolyte tout-solide/électrode (+)) clés de futures microbatteries tout-solides embarquées sur puce, compatibles avec une fabrication (additive) en salle blanche.

Decreasing the Energy Performance Gap and Thermal Loads in Residential Dwellings Using Machine Learning and Building Energy Modeling

The energy demand of the residential sector in Canada represents 12% of the total energy use. About 64% of such demand is assigned to space heating requirements. Adoption of energy-efficient systems is usually driven
by long-term savings. Many passive energy reduction measures haven’t been implemented due to the decreasing credibility of simulation software which lacks the ability to accurately predict energy performance. The deviation
of the actual energy consumption from the simulated one is termed as the energy performance gap (EPG). This research will study multiple residential dwellings categorized based on input variables relevant to a building’s
geometry, envelope, and site parameters. The actual energy consumption of these dwellings will be compared to that of simulated models to calculate the EPG. Artificial neural network will be employed to model the EPG in
correlation with the most dominant independent design parameters. Once EPG is determined using the developed model, an algebraic equation will be developed to better assess energy-efficient strategies by defining their exact
potential and true savings. The model will be validated using real-time thermographic images of a built prototype with a special emphasis on thermal bridging.

Deamination of cytosine and 5-methylcytosine in DNA by radical mediated oxidation

Deamination of cytosine (C) and 5-methylcytosine (5mC) lead to GC to AT point mutations, which represent the major fraction of spontaneous mutations in a variety of genomes. We propose that most GC to AT mutations arise from the initial oxidation of C and 5C by reactive oxygen species followed by deamination of the intrinsic exocyclic amino group. In this project, we will examine the effect of DNA sequence on the formation and subsequent rate-dependent deamination of several C and 5mC oxidation products in synthetic oligonucleotides using a combination of isotopic labeling and ultra-performance liquid chromatography coupled to tandem mass spectrometry. In addition, the ability of base excision repair enzymes to repair C and 5mC damage before and after deamination will be assessed in vitro with purified enzymes and the above oligonucleotides. From these studies, we will be able to correlate specific damage with mutations in human disease and disorders related to aging.

Zircon as a tracer of mantle processes and kimberlite magmatism

Zircon, the oldest mineral found on Earth, provides a unique record of geological processes through time. Its extreme chemical and mechanical stability helps preserving these records upon the mineral transfer to the Earth’s surface and weathering. Zircon is a ubiquitous accessory mineral in silica-rich continental rocks, which has long been used as a tracer of processes in the continental crust. However, a growing number of findings of zircon in (ultra)-mafic rocks provides strong evidence for stability of zircon in mantle settings. Kimberlites, the deepest mantle magmas, and the hosts of diamond deposits, also contain zircon, however its origin is poorly understood. The proposed experimental study will test if formation of zircon is not limited to silicic crustal systems but can happen in the mantle. The project aims to constrain the origin, conditions, and compositions of mantle melts/fluids parental to zircon, and, using the concentrations of trace elements in zircon, deduce the composition of kimberlite melt. Joining expertise in kimberlite research of Canadian team with zircon studies of French team will help addressing important questions of subcontinental mantle evolution, origin of enigmatic kimberlite magmas, and processes of metasomatic enrichments of continental roots in rare trace elements critical for modern technologies.

Improved Graphene Production by Rapid Thermal Exfoliation of Graphene Oxide for Application in Energy Storage

Graphene and related materials remain the most promising electrode materials and additives for use in energy storage devices such as batteries and supercapacitors due to the potentially high surface area, high aspect ratio and electrical conductivity. Unfortunately, it remains challenging to achieve single layers of graphene using scalable methods of production. The proposed work aims to design a flow-through reactor capable of rapidly expanding graphene oxide powders to reduced graphene oxide in order to study how precursor morphology and reactor conditions affect the yield of single layers produced by this high throughput method. This will allow the team to engineer improved, higher surface area electrode materials.

The effect of bovine colostrum supplementation on fitness, muscle mass, inflammation and immune function during intense training in rugby players

Bovine colostrum is the milk produced by cows immediately after calving. It contains high levels of proteins that improve immune protection and may act to prevent colds. During intense training, athletes often have compromised immune function. This may be especially true in club-level rugby players who abruptly start high intensity training in the spring in preparation for their competitive season. Our study will assess the effects of supplementing these players with bovine colostrum during this intense training. Thirty-six players will be recruited; half will consume colostrum during the 8 weeks of early-season training and half soy protein. We predict the bovine colostrum supplement will improve health during the training and increase fitness levels. The Saskatoon Colostrum Co. Ltd. is a leading producer of bovine colostrum supplement. This study will provide needed evidence for promotional material for marketing.
